Running Install Script (Microsoft .NET Framework

I've downloaded .NET 8.0 and can launch the game by manually using starttmodloader in the files but this forces open a command prompt window that will close the tmodloader window if i close that one

Dedicated server won't load mods, resets enabled.json on every startup

I am trying to set up a dedicated server on my linux machine. I have set up the dedicated server files according to the github page, including copying the enabled.json and install.txt files from the created modpack on game, and I have run the ./mange-tmodloaderserver install-mods command, which downloads the mods. However, every time I start the server, no mods are loaded, and the enabled.json file is reset to being empty.

tModLoader Crashing On Startup

When I try to launch tModLoader the console opens but closes a couple of seconds after. However, this issue is only happening with tModLoader, not Terraria, which works fine. I'm not sure why this is happening and have already tried a lot of different solutions, none of which worked: uninstalling both tModLoader & Terraria, deleting both entire folders, verifying the integrity of my files, redownloading Dotnet versions 6.0.100, 8.0.410, and 9.0.300, & deleting all workshop items (mods & resource...

Controller support disabled by default?

Anyone know how I can re-enable Terraria's built in controller support? I'm able to play regular Terraria with a steam controller quite fine, not sure why tmodloader disables it by default. When I load up tmodloader, the menu does not recognize my controller inputs, when I load into the game the same issue occurs.

In-Game instant crash. no error message. Logs are still here though.

I looked at other posts before posting here. I looked at troubleshooting guide also. Game slows down then crashes or random crash. Happens from to many entities. Playing the game long enough. Randomly. I am assuming memory leak but i don't know coding. read logs and found that the game can't handle wood and is crashing the game?...

Guys, why is my Terraria Calamity lagging? Like, I had an old notebook that ran Calamity at 60fps and it's relatively worse than my current PC. I would like someone who understands to help me

Cannot start server with Ethernet cable connection

So as the title says, my friend cannot start the server. We live in a dormitory so we cannot affect the router. And he uses the cable connection. At the beginning it didn't work and we didn't know why. After some time it started to work, so we could play. And now the issue is the same. When his pc is a hotspot (to which I connect my laptop) i CAN start the server. The server starts with using mobile data as well. But it DOES NOT when the cable is used. We really have no clue what's going on. Bu...

I need major assistance please; If you have any experience in recovering backups PLEASE DM

I've tried to read about it and watch a few videos but nothings worked yet, its my bro and I's world and if it's a little set back it'll be fine but everything would be gut wrenching we just made it to golem to put it in perspective a little, we're not very good...

Specific Mod Configuration for unique playthroughs

Basically I want to be able to set it up so that with certain characters and worlds I can utilize some mods that I have or find but not all of them like if I want one worlds to be purely Calamity and then the next one I want to be just Thorium or something without going through the hassle of having to turn the mods on and off every time I boot up that particular character and world?

Continously crashing!😭

Ran a check to find any corrupted files, found none. Updated my graphics card and got an FPS mod. I only have trusted mods installed, and only 1 content mod total. Yet every few minutes, I get kicked from the game. And it's probably worth noting that this didn't happen nearly as much earlier stage in my gameplay. But now it's getting absurd. I brushed it off before as "Awh, man. That sucks." Now it's basically "TModCrasher" and I'm actually losing it.💔
